Specification of Letters Patent. Pate t d pl 16 1922 Application filedDecember 8, 1919. Serial No. 343,302.

ing soldering irons, curling irons and other articles, and moreparticularly to such devices wherein alcohol is employed as the fuel.The invention is directed especially to a device to be used inconjunction with a solid alcohol fuel of which Sterno canned heat is anexample.

The objects of the invention are to provide a device wherein theintensity of the flame of the burning fuel will be increased.

. A further object is to provide a device in which the flame will beconcentrated on the article to be heated.

Another object is to provide a device which will act as a support forthe article to be heated, and to art as a wind shield.

These and further objects will more fully appear in the followingspecification and accompanying drawings considered or separately.

One embodiment of the invention is illustrated in the accompanyingdrawings in which like parts in all of the several fi ures aredesignated by similar characters 0 reference, and in which Fig. 1 is alongitudinal section of the preferred embodiment of my invention, takenon the line indicated by 1-1 of Fig. 3.

Fig. 2 is a front elevation of the heater.

Fig.3 is a top plan view of the heater partly in section, the sectionbeing taken on the line 3-3 of Fig. 1.

In the embodiment of the invention illustrated, the invention isillustrated in conjunction with a can or receptacle 1 adapted to containa solidified alcohol fuel. As shown the can 1 may rest within a base 2which may be rested upon the ground or other support 3.

The fuel. receptacle may be of any desired dimensions or configuration,that illustrated being a cylindrical can having an annular member 1carried at one end thereof and provided with a circular flame openingtherein. In the embodiment illustrated the flame opening is defined by adepending, circular flange 5 on the member 4 and adapted togetheropening 7. The lower to form the seat for a friction cover (not shown)as is common.

The heater of this invention preferably comprises a hollow body of thinsheet metal 6 o cylindrical form. The upper or top wall of the body isprovided with a draft portion of the body is contracted to form a throat8 which may be of approximately the same area and shape as the draftopening 7 Below the throat 8 the material of the heater is formed to aflat horizontal wall 9 of annular form, the outer edge of which extendsdownward to form a short cylindrical wall 10 which is provided with aseries of perforations 11. An annular flange 12 extends outward from thelower edge of the wall 10, and a depending cylindrical skirt 1.3 extendsdownward from the outer peripheral edge of the last mentioned wall. Aseries of perforations 14. is formed in the material of the heaterpreferably at the junction of the flange 12 and the skirt 13.

The area and configuration of the opening defined by the skirt 13 issuch that the lower edge of the shirt may rest upon the memberll-between upper edge of the wall of the can 1 and the flame opening 5and encircling the latter whereby the flame issuing from the openingwill be directed upward through the throat 8 into the body 6.

In the vertical wall of the body 6 is formed an opening 15 which may, asshown, he of rectangular shape and of a size sufficient to permit of theentrance of the head 16 of a soldering iron, or other article to beheated. At the lower edge of. the opening 15 a notch 17 is provided,which may conveniently be of triangular shape as shown. When a solderingiron is to be heated in the device the tang or shank 18 thereof willrest within the notch and be prevented from movement relatively to thebody. The handle 19 of the soldering iron, when the latter is inposition to be heated, may rest upon the support 3.

The notch 17 is of triangular or wedge shape in order that bodies orimplements of different diameters may rest therein, and the wedge shapeof the notch will further act to retain the implement in position by thewedging action of the tang in the notch.

The air entering the perforations 11 and 14 will supply the oxygennecessary to support combustion and will be directed against thereof,but it is to be understood that the the axial center "plied as shown inFig. 1.

r and 14; Y will support part not consumed be directed upward in a to:remain in the v handle 19 resting on the support will act as a prop toin the support, and means for support for the body,

the flame in such a manner that the latter will be formed into acylindrical column in ofthe body 6. This action of theair entering theperforations 11' and 14 will be supplemented by the relativedispositions of the throat and draft openings. The base 3 is for thepurpose of stabilizing thecaniand heater, but it is obvious that thesame may be dispensed with if desired.

The operation is as follows y The fuel 20 is, ignited and the heater ap-The head of a soldering iron, for example, is inserted throughthe'opening 15 with its tang 18 engaging the notch resting on thesupport 3.

17 and its outer extremity The air drawn in through the openings 11combustion and that hollow vertical column and confine the flame into a1 vertical cylindrical column. The shape :of the throat will furtherconfine the flameland direct it upward toward the draft opening 7.. Theiron 16 will be positioned directly in the column of. the flame and atthe point of greatest heat intensity.

The shape of the notch will cause the iron desired position and theprevent upsetting of the can and heater. 7 i

' In accordance with the provisions of the patent statutes, the

principle of the inven .tion has been described together with what isnow considered to be the best embodiment apparatus shown is merelyillustrative and the invention may be carried out in other ways.

Having nowdeseribed the invention, what is claimed as new and desired tobe secured by Letters Patent is'as follows 1. A heater comprising ahollow body and an integral portion forming a support for the body,there being a contraction between the body and support and forming athroat, a draft opening in the body in alinement with the throat, therebeing draft openings gripping and supporting anarticle to be heatedwithin the body, and between the throat and the alincd draft opening.-

42. A heater comprising a hollow body, a

there being a contracted portion between the body and sup port andforming a throat, there being a draft opening in the body in alinementwith article,

in the body insertion of an the throat, there being draft openings inthe support, there being an opening in the body for the insertion of anarticle to be heated, there being an open notch in a wall of saidopening adapted to receive a portion of said said article beingpositioned in the opening by engagement thereof with the side walls ofthe notch.

3. A heater comprising a hollow body, a support for the body, therebeing a contracted portion between the body and support and forming athroat, a d aft opening in the body in alineinent with the throat, therebeing an opening in the body for the insertion of an article to beheated, there be ing a tapered notch in a wall of said opcning adaptedto receive a portion of said article, there being draft openings in thesupport, and means for supporting the article to be heated within thebody and between the throat and the alineddraft opening.

4. A heater comprising a hollow body. a support for the body, therebeing a contracted portion between the body and support and forming athroat, a draft opening in alinenient with the throat. there being anopening in the body for the article to be heated. said opening beingperpendicular to the throat and alined draft opening. there being atapered notch in a wall of said opening adapted to receive a portion ofsaid article, there being draft. openings in the support, said notchbeing the only means carried by the body for supportin the article.

5. A. heater comprising a rece .)taclc adapted to contain fuel. anannular member forming the top of the receptacle, a hollow elementresting on the member and in communication with the receptacle, saidelement comprising a body, there being a contraction between thereceptacle and body forming a throat, there being a draft opening in thebody in alinement with the throat. draft openings in the element betweenthe receptacle and the throat, there being an entrance in the bodybetween the throat and the ,alined draft opening. one side of said en-GEORGE STANLEY MEIKLE. itnesses A.
